Introduction. Chronic prostatitis (CP) is the most common cause of a disorder of not only sexual, but also reproductive functions in men, which is caused by a decrease in the quality of the ejaculate and is confirmed by a deterioration in spermogram parameters, up to oligoasthenoteratozoospermia and azoospermia. In such a situation, the onset of pregnancy in the natural cycle is impossible - even with a completely preserved reproductive function in a woman. As an active substance in the recovery of men with chronic prostatitis associated with secondary infertility, we proposed oxidised dextran in the form of a pharmaceutical composition, which was developed at Federal Research Centre for Fundamental and Translational Medicine, Novosibirsk, Russia; and produced by ANDROEXPERT Research and Manufacturing Company LTD, Novosibirsk, Russia.
The purpose of the study was to evaluate the dynamics of spermogram parameters as a result of the use of suppositories with oxidised dextran «ANDROEXPERT SV1» in men with chronic prostatitis associated with secondary infertility.
Material and methods. The study included 52 patients with chronic prostatitis associated with secondary infertility. The mean age of the patients was 32±2.2 years. The examination of patients was carried out in accordance with the algorithm recommended by the Russian Society of Urology, the European Urological Association and the standard of primary health care for chronic prostatitis (Appendix to the order of the Ministry of Health of Russia No. 775n of 09.11.2012).
The patients were divided into two groups: the 1st group of patients received oxidised dextran rectally once per day for 10 days, then 20 days every other day; The 2nd (comparison group) received a placebo in the form of rectal suppositories consisting of cocoa butter in a similar way.
Results. The volume of ejaculate among patients of the 1st group increased from 2.54±0.15 to 3.13±0.18 (ml), which amounted to 23.23%; p<0.05. The sperm concentration indicator increased from 26.40±4.18 to 41.12±5.37 (million/ml) - by 55.75%; p<0.05, which led to an increase in the total number of spermatozoa in the ejaculate by 88.5%, from 65.47±8.41 to 123.41±12.33 (million pieces); p<0.05. The number of leukocytes in the same group decreased by 2.8 times: from 1.25±0.17 to 0.44±0.10 (million/ml) - by 64.80%; p<0.05. The indicator of the severity of sperm agglutination decreased by 3 times: from 0.52±0.07 to 0.17±0.03 - by 0.35 arb. units, which was 67.31%; p<0.05. The indicators of the spermogram in patients with chronic prostatitis of the second group did not change in the course of treatment.
Conclusion. Assessing the dynamics of spermogram parameters as a result of the use of «ANDROEXPERT SV1» in men with chronic prostatitis associated with secondary infertility, there is a decrease in the number of leukocytes and a significant improvement in the parameters of the ejaculate, both its general properties and the main characteristics of spermatozoa. Thus, ANDROEXPERT SV1 suppositories show high clinical efficacy and safety in monotherapy and may be promising when choosing the management tactics for this group of patients.
